The properties of air and the water contained in it at different temperatures arranged in the form of a chart which is called a psychometric chart. In particular it shows the quantitative interdependence between temperature and humidity. It is useful in the planning, specification and monitoring of cooling systems.

What is the tensile strength of .375 bolt?
Tensile strength is a material propery, it does not depend on size. Look at a material chart to find its yield and tensile strenghts. Then use the stress equation, Stress = Force / Area to determine if your .375 bolt can handle the force on it. If your bolt is in shear, you need to find Shear strenghts.
What are Constant quality lines hvac?
It is the percentage of a refrigerant that is either liquid or vapor. So looking at a R-22 Enthalpy chart, the first number at the base you see is 10. That 10 represents the percentage of vapor to liquid. In other words, you have 90% liquid at that point, and 10% vapor. As you move across the chart from left to right, that would be equivalent to the refrigerant boiling... as it goes through latent heat and the refrigerant boils off, the percentage of liquid to vapor gets smaller. When you get to 9... that is equal to 90% vapor/ 10% liquid. The outer lines of that dome shape would be equivalent to, on the left hand side, absolute liquid and all the way to the right hand side, absolute vapor.
I need a spectacle blind flange rating chart is there one?
A few months ago, I was asking the same question. I did a search online to see if I could find a pressure rating chart and came across the Sweco Fab website. The fact of the matter is that the charts on the Sweco Fab are a little confusing and do not provide accurate information. I tried to contact Sweco Fab to get more information and asked if they could send me a pressure rating chart. They never responded to my request. There are a lot of variables that go into determining the pressure rating of a spectacle blind. Size of pipe, flange size, type of material, corrosion resistance, thickness of blind, etc. Your best bet is to manually calculate the pressure rating by using equation (15) in section 304.5.3 found in the ASME B31.3-2002 specification. If you are using a standard thickness you can solve for pressure. I would recommend using the standard thicknesses that can be found in ASME B16.48-2005 (Line Blinds) specifications. If you don't have the time, ability, or resources to figure out the pressure ratings yourself, you can also contact manufacturers of spectacle blinds and request the information. I didn't have any luck with Sweco Fab, Inc. but I'm sure there are manufactures out there that are willing to help.
Who invented the psychrometric chart?
Dr.Willis Carrier
What is the temperature at which air is saturated?
Dew Point (Refer to a psychrometric chart)
Where can one use a psychrometric chart?
Psychrometric charts are used to measure the physical and thermal properties of moist air. They are mainly used with greenhouses and livestock building troubleshooting.
How many properties must be known to locate an unknown property on the psychrometric chart?
One
Name the two unknowns that are easiest to obtain for making plots on the psychrometric chart?
No
What will happen if a technician uses a sling psychrometer that has a perfectly dry wick on the wet bulb thermometer?
If a dry wick is present the temperature shown on both thermometers will be the same. This data, when entered into the psychrometric chart, will indicate that the air has 100% relative humidity.

What Is the realitive humidity of saturated air?
The maximum amount of water contained in air at various temperatures and pressure is indicated on a psychrometric chart. The carrying capacity changes with these parameters. The actual humididty can be read out from wet and dry bulb thermometer temperature measurement. However at 100% carrying capacity y the relative untidy is always 100 percent.
What is the use of psychrometric chart?
It is a very powerful and practical tool for getting different physical and thermodynamic properties for any gas-liquid mixture. Mainly, we are interested in the steam-air analysis. Parameter like dry-bulb temperature, wet-bulb temperature, specific volume, specific enthalpy, relative humidity, humidity ratio, and dew point temperature can be all gotten from this chart. For a practicing engineer who deals with moist air calculations, it is easier to pack a single, pocket-size chart, than to carry around the whole thermodynamics book - a matter of convenience. Different engineering applications deal with this chart in conditioning, heating, ventilation, aviation..etc. So, this chart is really beneficial. Thanks to "the father of cool", Willis Carrier, who designed this magical tool in 1904.

What is the condensation point of the water?
The condensation of water from air (dew point) depends on temperature, pressure and the relative humidity of the air. It is not a single point for all conditions. For a specific set of conditions this data may be determined from a Psychrometric chart
